Thrust Ability Diagram (Auto Thruster Window)
If the vessel’s heading or position or both are controlled manually, the Thrust Ability Diagram displays the following
information:
– the desired values for forces vector
F
demand
and moment
M
demand
;
– the actual values for forces vector
F
actual
and moment
M
actual
;
– the estimated disturbance force vector
F
disturb
and moment
M
disturb
;
– possible combinations of the forces vector
F
and moment
M
The Thrust Ability Diagram works in terms of forces vector
F
and moment
M
, and is based on the Thruster Allocation
Function usage (see Section 6.3, page 115).
The Thrust Ability Diagram contains some common data shared with Capability Analysis Function and the Conse-
quence Analysis Function but, obviously, doesn’t replace them.
The Thrust Ability Diagram is displayed at the top of the Auto Thruster Window.
NOTE!
The Thrust Ability Diagram view corresponds to the joystick orienta-
tion. The orientation (axis direction) is displayed at the top left corner.
